SU2 process returned error '139' while running hypersonic shape optimization

meoazz · November 3, 2022, 13:45

Hello everyone,

I am trying to run a 2D shape optimization case in hypersonic regime, using discrete adjoint.

Firstly, I have performed the simulation in supersonic regime and everything works.

But when I try to switch to the hypersonic case (using SOLVER= NEMO_EULER) the simulation blows up after the first direct step, during the adjoint one.

The error that appears in the terminal is shown in Fig_1

The log_Adjoint.out is reported in Fig_2

Since it seems to be an error related to the SU2_CFD_AD function, I also tried to force this command directly inside the DESIGN/001/ADJOINT_DRAG folder: the error that appears in the terminal is shown in Fig_3

Do you have any ideas on how I can solve the problem?
Thank you in advance

Hi Meoazz,

Thanks for using SU2-NEMO. At this time, NEMO does not have the capability for the discrete adjoint. I am currently working on finalizing the capability, including verification and validation; it should be available in the coming months.
